The group found that, on average, people living in Manhattan travel 2.5 miles most days, compared to five miles in Los Angeles. But we also found that when you look at the longest trips people make, people that live in New York go significantly further, 69 miles on a weekday compared to 29 in Los Angeles.

Inside each of us are monsters and angels- there are no divisions between good and bad people- and I've seen how those times of insecurity can make us do terrible things to each other.

To understand what we're facing in the 21st century, we need to look back in history. It has not always been the case that women were considered inferior or subordinate to men. The myth of women's inferiority is the product of a social system that has produced and fostered countless other inequalities, inferiorities, degradations, and discriminations.

Status often has what's called an accumulative advantage property. If you get just a little bit of a head start, you can end up racing far ahead. So you end up with very small differences in quality or merit that get amplified over careers or competitions, eventually becoming very large differences over time.
